LibWeb: Rename is_scrollable() to could_be_scrolled_by_wheel_event()

Browse source 
Previous name for misleading because it checks if box could be scrolled
by user input event which is diffent from checking if box is scrollable.
For example box with `overflow: hidden` is scrollable but it can't be
scrolled by user input event.
